 // =============> explain this error message here
-
+// The error message is indicating that there is a syntax error in the code because we are trying to use a number '3' as a parameter name in the function declaration, which is not allowed in JavaScript. Parameter names must be valid identifiers, which cannot start with a number. To fix this error, we need to change the parameter name to a valid identifier, such as 'num' or 'x'. So we would change the line to: function square(num) { return num * num; }  
 // Finally, correct the code to fix the problem
 
 // =============> write your new code here
+function square(num) {
+  return num * num;

+console.log(square(3));
